I don't believe there is an innate zero-sum bias. Why would humans be hunting in groups 200,000 years ago if we evolved to be zero-sum thinkers? I find too many people on HN use the zero-sum bias argument against everything because Paul Graham said so. Some resources are zero-sum, and remain so through the last century of technological progress (which has seen most of mankind's improvements). Land ownership (especially coastal properties) is ever diminishing. Cities still fight over water (desalination is expensive). Oil, a new zero-sum resource, has been the cause of many wars. It is only in the utopia of software development (where duplication is cheap), that people are blind to this. If the population ever outstrips availability of crucial goods like land, water, or food, you will see your software and webapp sales plummet to 0 no matter how hard you work on it.
